Electrical Misc

Exterior devices

  • AC In: IEC for 120 to 220VAC
  • DC In: 12VDC to 30VDC 2 Pin connect that mates with whats on the GP solar blanket.
  • DB9 for RS-232??

switch batteries.

  • Future RJ45 10/100 ethernet connection

Software

  • will be updated soon

Mechanical

  • Density. Getting as many batteries as possible in as small a footprint is a goal.
  • Physical Safety. Its got to be stable and hold lots of heavy batteries but not be able to fall over on top of a child. Who might be trying to climb on it to get his battery.
  • Stackable. More vertical space is available than floor sq footage so an idea was to make them stackable. But see above point.
  • Heat dissipation. Each battery needs 15W worst case and most of that power will be dissipated into the batery. I expect the electronics/battery to dissipate less than 1W/battery. PSU at 300W @ 85% efficiency is 45W.
  • Enclosure. Metal. Except perhaps for some plastic for the battery holder. Having metal available to heatsink to should help in keeping the electronics from burning up in hot countries.
